1/4" MEG Nozzles Sized to Your Machine

MEG nozzles are the threaded screw-in spray tips contractors run in surface cleaners, nozzle holders, and dual lances. We keep every angle from 0 to 65 degrees on the shelf in Gaithersburg, in orifice sizes that match real pump output. Not sure which orifice number your machine needs? Call 301-519-9274 with your GPM and PSI and we will size it before you spend a dollar.

How to Read a 1/4" MEG Nozzle Number

Every MEG nozzle carries a four or five digit stamp, and once you can read it you will never buy the wrong tip again. The first two digits are the spray angle. Everything after that is the orifice size. A 2504 throws a 25 degree fan through a number 4.0 orifice. A 15055 is a 15 degree fan with a 5.5 orifice. The color bands you see on quick connect tips do not apply here, so trust the stamp, not the finish.

The orifice number comes from flow at a reference pressure. A number 4.0 orifice passes about 4 GPM at 4,000 PSI. Bigger number, bigger hole, more flow at less pressure. That single number is what protects your pump, so get it right first and pick the angle second.

Match the Orifice to Your Pump, Not the Other Way Around

A nozzle chart crosses your pump's GPM against the PSI you want at the tip. Run an orifice that is too small and the machine builds pressure past its rating, the unloader lives in bypass, and the water in the pump head heats up until the packings give out. Run one that is too big and pressure falls off a cliff even though the engine sounds fine. When a customer tells us their brand new machine feels weak, the tip is the first thing we check.

Sizing for a surface cleaner is the same math with one extra step. Find the orifice your machine calls for on the chart, divide it by the number of nozzles on the bar, and round up. An 8 GPM machine that charts at a number 8.5 orifice runs two 4.5 tips on a two-nozzle surface cleaner. Undersize them and you will strip your pump instead of your concrete.

Pick the Spray Angle by Surface

0 degree hits hardest and cuts the narrowest path, so save it for spot work on concrete and steel. 15 degree strips paint, gum, and heavy buildup. 25 degree is the workhorse angle for flatwork and general cleaning. 40 degree spreads the impact for siding, wood, and vehicles. 65 degree is the soap angle, built to drop pressure enough for a downstream injector to pull chemical.

Prices move, so call if a job depends on it. The stainless tips above come in multiple orifice sizes on each product page.

From the Field

The cheapest part on your rig does the most damage when it wears. As the orifice erodes, the fan widens, tip pressure drops a few hundred PSI, and guys compensate by holding the wand closer and working slower. A $5.39 tip fixes what looks like a $900 pump problem. The other habit worth breaking is clearing a clogged tip with a paper clip or torch tip cleaner, because reaming the orifice oversizes it for good. We stock a brass nozzle unclogger tool that clears debris without cutting metal. And if your surface cleaner leaves zebra stripes, look at the vane style I-MEG nozzles before you blame the bar. The internal vane tightens pattern edges so passes overlap clean.

Frequently Asked Questions

What do the numbers on a MEG nozzle mean?

The first two digits are the spray angle and the remaining digits are the orifice size. A 2504 is a 25 degree fan with a number 4.0 orifice. A 4007 is a 40 degree fan with a 7.0 orifice.

What size MEG nozzle does my pressure washer need?

Cross your pump's GPM against its rated PSI on a nozzle chart. A 4 GPM machine at 4,000 PSI takes a number 4.0 orifice. Call 301-519-9274 with your machine specs and we will read the chart for you.

How do I size MEG nozzles for a surface cleaner?

Find the single orifice size your machine calls for, divide by the number of nozzles on the bar, and round up. An 8 GPM machine that charts at 8.5 runs two 4.5 tips on a two-nozzle surface cleaner.

What is the difference between a MEG nozzle and a quick connect tip?

A MEG nozzle has a 1/4 inch male thread and screws into a holder, a surface cleaner bar, or a lance. A quick connect tip is a MEG style nozzle already pressed into a snap-in coupler body. Threaded MEGs cost less and seat more securely in equipment that vibrates.

What happens if the nozzle orifice is too small?

The machine runs over its rated pressure and forces the unloader into constant bypass. Bypass water recirculates and heats up fast, and hot water is what cooks pump packings. An undersized tip can take out a pump in one long afternoon.

When should I replace a MEG nozzle?

When the fan looks wider than it used to or tip pressure drops with no other cause. Orifices wear open with use, faster with hard water or downstream chemical. Full time crews swap tips every few months. At these prices, replace on schedule instead of on failure.
